This document provides a tutorial on how to connect and configure a 3G module on various operating systems, including Linux, Windows XP, Windows 7, and Mac OS X using a virtual machine. It describes steps such as installing drivers, identifying the correct USB port, using terminal programs to send AT commands to the module, and configuring the module for modem functionality using Wvdial on Linux.

1. 3G module tutorial
Linux
Plug in the device, and execute dmesg in console. With this we can see if we have
the drivers of the device installed or not.
$:/etc$ dmesg
generic-usb 0003:05C6:F006.0003: hiddev96,hidraw2: USB HID v1.10 Device
[SimTech, Incorporated SimTech SIM5218] on usb-0000:00:1d.1-1/input0
Not recognize the device, we install the necessary drivers.
Execute lsusb, this command show a list of devices connected to USB port:
$:/etc$ lsusb
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 008: ID 05c6:f006 Qualcomm, Inc.
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 0e6a:6001 Megawin Technology Co., Ltd
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
In this list, we can see:
the vendor: 0x05c6
the product: 0xf006
With this parameters we will configure the file modules in path /etc/. For
configuring we have to execute:
$:sudo gedit /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.
lp
usbserial vendor=0x05c6 product=0xf006

We can communicate with the device using AT commands, for this we use Cutecom
for example:

3. 3G module tutorial
Now the computer recognize the module SIM5218. We can use this module in
different ways.
For use as a modem, we must follow these steps:
• Installing Wvdial in our Linux distribution, if not installed:
sudo apt-get install wvdial
• Configuring WvDial:
1. Once you have run wvdialconf, you need to edit the /etc/wvdial.conf file to
reflect the phone number to dial, and your username and password.
2. Open up /etc/wvdial.conf in your favorite text editor. It should look something like
this:
[Dialer]
Modem = /dev/ttyUSB2
Modem Type = Analog Modem
Baud = 115200
ISDN = 0
Stupid mode = 1
Idle Seconds = 0
Init2 = ATZ
Init4 = AT+CGDCONT=1,"IP","my_APN"
Password = "my_password"
Phone = number of telephone
Username = "my_username"
Dial Command = ATD
3. Save your changes and exit out of the text editor.

• Run wvdial
$:/etc$ wvdial /etc/wvdial.conf
--> WvDial: Internet dialer version 1.60
--> Warning: section [Dialer /etc/wvdial.conf] does not exist in wvdial.conf.
--> Cannot get information for serial port.

5. 3G module tutorial
Windows XP
Plug in SIM5218 to the computer. First step is install the drivers to use the device.
Drivers can be download to: http://www.cooking-
hacks.com/skin/frontend/default/cooking/pdf/WindowsDrivers_SIM5218_2.4.00.rar
As seen in “other devices” there are five that are not assigned any driver, and
therefore can not be detected by the operating system.

To install drivers for each device, we must select it by double click. And press the
Update Driver button.
Select install from a list or specific location.

8. 3G module tutorial
Now, drivers are installed. The device is recognize.
Once the device is connected and recognized by the operating system. We can use
it.

9. 3G module tutorial
To communicate with the module has been decided to use the Hyperterminal
program to Windows XP. This program will allow us to communicate with the module
through AT commands or use it as modem.
Run Hyper-terminal, and create new connection.
For use the module with AT commands, First, we must find what is the port to
connect to send AT commands.

11. 3G module tutorial
In case you want to configure the module as a modem SIM5218E should create a
new connection and choose the port, SimTech HS-USB Modem 9000.

12. 3G module tutorial
Windows 7
Plug in SIM5218 to the computer. Check drivers are installed, if they is not installed,
you must do it.
Computer Management can find that devices are recognized and which need a
driver. In this case one can see that there are five devices that have no driver.
Before installing the drivers for the SIM module, we must check what version of
operating system we have. Depending on the version of operating system we use the
device drivers 32 or 64 bits.

13. 3G module tutorial
Now, we install drivers, We select for this option in the sub menu the Update Driver
Software. We repeat this process for the five missing drivers.
We look for the drivers we downloaded, and select it.

14. 3G module tutorial
Pressed the button accept. Drivers are installed.
To communicate with the module SIM5218 through AT commands, we will need the
Hyper-terminal program. This program can be found at the following address:
Once installed Hyper-terminal, create a new connection.

15. 3G module tutorial
Configure the connection as it appears in the figure 7. The port you have to choose
to communicate with the module through AT commands, so get looking at the system
administrator. This time the port for communications with AT commands is port COM6.
